Course
Description:

THIS COURSE IS ALL ABOUT DESIGN, NOT CALCULATIONS. LEARNING OUTCOMES INCLUDE AN INCREASE IN YOUR ABILITY TO UNDERSTAND HOW STRUCTURES WORK, AND DETAIL THE SAME. PORTFOLIO WORTHY DESIGN PROJECTS.

Using an international database of case studies this course examines in detail the architectural design, specification, fabrication and construction process for Architecturally Exposed Structural Steel (AESS). It references the standards that were developed by the Canadian Institute of Steel Construction. Lectures will address topics including, the AESS Category Approach, fabrication standards and practices, project communication, tensile structures, diagrid structures, curved steel, castings, pedestrian bridges, steel with glazing, steel with timber. The work of the term will use current steel based competitions to explore detailed design application of the material.

The term’s
knowledge will focus on DESIGN PROJECTS that requires the students
to design and detail architecturally exposed structural steel systems, connections and buildings.

Students will
· keep a detailed sketchbook of examples and details addressed
in class,
· in teams of 2 (masters) or 3 (undergrad) students, complete the CISC Design Competition - LINK

PLUS one of
· in teams of 1 or 2 (masters) or 3 (undergrad) students, complete the AISC/ACSA Design Competition - OPEN Category. (We are not doing the housing competition as it is too complex for the course and time available)
or
CTBUH Skyscraper Competition (details yet to be announced, link to 2017 version)

The overall intention is to provide you with a high level appreciation of steel structural systems and an adeptness for detailing that is appropriate to the specific project and building type. The work
of the term is intended to provide you with some signficant pieces for your portfolio.

The majority of the project work has been designed as group projects to keep it manageable and within the suggested constraints of an elective. If there are compelling reasons for tackling the work individually, these can be discussed.

2

ARCHITECTURALLY EXPOSED STRUCTURAL STEEL:
The development and details of the new system created by CISC to clarify the design, construction and fabrication of AESS systems.

3

APPLICATIONS IN AESS:
A look in more detail at several Canadian buildings using the CISC method of Categories and Characteristics. Topics will also address finishes and corrosion protection as these impact the detailing of an exposed structure.

4

SPAN:
A look at different ways that we create long spans with structural systems. Types will include truss systems, spaceframes. Applications will include buildings and pedestrian bridges.
Discussion will focus on preparation for the SSEF "LINK" Competition.

5

TENSILE STRUCTURES:
An examination of a range of applications of tension systems for building structures, canopies, roofs and pedestrian bridges.

COMPETITIONS:
A review of previous winning competition schemes. A strategizing session to understand the perspective of the jury, role of the brief and to plan a strategy for winning!

6

CASTINGS AND CURVES:
Castings of the 21st century are very different than the elaborate castings of the 19th century. A look at the application of modern cast steel via several case studies.
Curved structures can be achieved via several means, all related to the scale of the building, budget and technical means available.

7

STEEL AND GLAZING SYSTEMS:
An examination of some of the newer cable type glazing systems to see how these work with AESS systems. The tolerances in glazing systems are even tighter than for finely detailed AESS structures, and these systems are often used together.

LATTICE SYSTEMS, DIAGRID STRUCTURES AND BRACING SYSTEMS:My This lecture will look at many of the case studies covered in my book on Diagrid Structures in detail, along with the method of design established in the book. We will also look at the design of bracing systems for buildings that can also be architecturally expressed. A new Canadian designed system used post quake in Christchurch, New Zealand will be discussed. Bracing systems for tall buildings will be introduced.

9

STEEL AND TIMBER SYSTEMS:
A look at some signficant projects that have used exposed steel and heavy timber or glulam. Steel and timber undergo very different thermal and moisture related movement, so this must be taken into account when detailing the systems.

Note: ACSA/AISC Registration deadline is March 30. We need to register our teams.

10

COMPOSITE STRUCTURAL SYSTEMS FOR TALL BUILDINGS:
This lecture will reflect some ongoing research I am doing with the Council on Tall Buildings and Urban Habitat to look at variations in the combinations of steel and concrete as composite systems. This material should feed well into the tall buildings competitions.

Apr
??

An extra session to be arranged at a mutually convenient time for consultation on the final design project.

Work to date to be submitted for the AISC/ACSA Competition or Skyscraper Competition. The final competition submission is not due to ACSA/CTBUH until x. A provisional grade will be used for end of term grading purposes. This can be revised to account for the final competition entry. Submission via LEARN.

Fully graded date for UW is May 20, so I need your projects submitted for grading by May 15 if you wish other than an IP grade on your transcript.

Reference Texts and other
Materials:

These texts will be on reserve in Musagetes. We have at most 2 copies of each book so you are not to remove them from the library to your personal shelves for the term. They are all available on Amazon. If you were to purchase just one for the course, the AESS one would be the most directly related.

Evaluation:

The final term grade will
consist of an average of submitted work as follows.

Late Penalties:
Projects or assignments submitted after the due date or due time will be penalized 5% per calendar day of lateness, with no maximum.

SKETCHBOOK:
10% You are required to keep a sketchbook/notebook for this class. It will be graded /5 for evidence of class attendance and /5 for
completeness/coherence of said notes. As the focus of the course is on steel detailing, the lecture will be paused at several points during the class to allow adequate time to sketch the details on the screen. Approximately 3 to 4 detailed sketches per lecture. Pause time will vary. If you miss a class, you lose
both the mark for attendance as well as the potential mark for the
quality of those notes.

SSEF Competition (mandatory):Three board submission as per their requirements. 45%

ACSA/AISC Competition:Four board submission as per their requirements. 45%

or

CTBUH/Evolo Competitions:
One board as per their requirements.
45%

or

Masters students can request to have a particular competition that might be better tuned to their thesis investigation as the second competition requirement.

Avoidance of Academic
Offenses

Academic
Integrity:To
create and promote a culture of academic integrity, the behaviour
of all members of the University of Waterloo is based on honesty,
trust, fairness, respect and responsibility. [Check www.uwaterloo.ca/academicintegrity/for more information.]
Grievance: A student who believes that a decision affecting
some aspect of his/her university life has been unfair or unreasonable may have
grounds for initiating a grievance. Read Policy 70 - Student Petitions and Grievances,
Section 4, http://www.adm.uwaterloo.ca/infosec/Policies/policy70.htm
Discipline: A student is expected to know what constitutes academic
integrity, to avoid committing academic offenses, and to take responsibility
for his/her actions. A student who is unsure whether an action constitutes an
offense, or who needs help in learning how to avoid offenses (e.g., plagiarism,
cheating) or about “rules” for group work/collaboration should seek
guidance from the course professor, academic advisor, or the Undergraduate Associate
Dean. When misconduct has been found to have occurred, disciplinary penalties
will be imposed under Policy 71 – Student Discipline. For information on
categories of offenses and types of penalties, students should refer to Policy
71 - Student Discipline, http://www.adm.uwaterloo.ca/infosec/Policies/policy71.htm
Appeals:A student may appeal the finding and/or penalty in a decision
made under Policy 70 - Student Petitions and Grievances (other than regarding
a petition) or Policy 71 - Student Discipline if a ground for an appeal can be
established. Read Policy 72 - Student Appeals, http://www.adm.uwaterloo.ca/infosec/Policies/policy72.htm
